Multiple frequency antennas with reduced space and relative assembly

Abstract

The disclosed embodiments of the present invention include an antenna element having a generally low profile and providing a larger bandwidth. The disclosed embodiments include antenna elements having a top section with at least one cutout. Each cutout is provided with one or more tongues therein. The tongues extend from an edge of the cutout inward. The tongues may be coplanar with the top section or may be positioned between the top section and a bottom plate. Each tongue may be positioned separately to produce the desired antenna element characteristics.

1. An antenna element, comprising:
 a bottom plate;  
 a top section positioned above the bottom plate and having at least one cutout therein, the top section being positioned substantially parallel to the bottom plate; and  
 one or more tongues extending from an edge of the at least one cutout, the one or more tongues being positioned below a plane of the top section, the one or more tongues including a vertical extension connecting a horizontal tongue portion to the top section.  
 
   
   
     2. An antenna element according to  claim 1 , wherein the vertical extension is substantially perpendicular to the top section. 
   
   
     3. The antenna element according to  claim 1 , wherein each cutout has a substantially rectangular configuration. 
   
   
     4. The antenna element according to  claim 1 , wherein the top section includes a single cutout. 
   
   
     5. The antenna element according to  claim 4 , wherein the single cutout is provided with a single tongue. 
   
   
     6. The antenna element according to  claim 4 , wherein the single cutout is provided with a plurality of tongues. 
   
   
     7. The antenna element according to  claim 6 , wherein each of the plurality of tongues extends from the same edge of the cutout. 
   
   
     8. The antenna element according to  claim 6 , wherein the plurality of tongues includes tongues extending from the different edges of the cutout. 
   
   
     9. An antenna element assembly, comprising:
 a base section having a bottom plate and a top section positioned above the bottom plate, the top section having a module-receiving opening therein; and  
 a tongue module adapted to be accommodated within the module-receiving opening, the tongue module comprising: 
 a top surface with at least one cutout therein; and  
 one of more tongues extending from an edge of the at least one cutout.  
 
 
   
   
     10. The antenna element assembly according to  claim 9 , wherein the module-receiving opening is substantially rectangular and is located in a central region of the top section. 
   
   
     11. The antenna element assembly according to  claim 9 , wherein the cutout is substantially rectangular. 
   
   
     12. The antenna element assembly according to  claim 9 , wherein the module-receiving opening is U-shaped. 
   
   
     13. The antenna element assembly according to  claim 12 , wherein the tongue module includes a vertical flap extending downward from an edge of the top surface.
